Taking advantage of vacated drug-research labs and offices about 15 miles away, Dow Chemical Co. will relocate 800 employees in its Spring House campus in Montgomery County to a Pfizer facility in Collegeville.
The plans had been rumored for months, and employees will begin moving in January. Dow, based in Midland, Mich., purchased Rohm & Haas in a highly contentious deal in the midst of the financial crisis of 2009. Rohm & Haas' research labs had been based in Spring House since 1963.
Dow has no current plans to add jobs to the research operation, which is now part of its Advanced Materials division. But Dow indicated Thursday that the new facility would provide room for expansion. Advanced Materials is leasing 750,000 square feet in Collegeville. Pfizer, a global drug company, is maintaining operations in some parts of the facility.
